In the beta I could set the video scaler in MEcoder to 1920x1080 and while using the Avisynth/MEcoder engine it would still upscale, but this doesnt seem to happen with 1.03While using the MEcoder engine in 1.03 it will upsale but not with Avisynth/MEcoder.

yes I changed that because that's not the role of mencoder to change avisynth video resolutionif you want to do some scaling with AviSynth/Mencoder, you must customise the AviSynth script and use Avisynth functions:

I did try it with ffdshow a while ago but found the preformace lacking.I just tryed to upsale with the last beta to see how the new mecoder would handle it and was quite surprised that it didnt skip a beat I olny hope that upscaling with avisnyth is also as quick.

That worked a treat, thanks guys.I might have been a bit too hopeful using Lanczos4Resize very chopy, BicubicResize and spline16/36 seem ok from the limited testing I have done.Also ffdshow seems quite happy to upscale now as well, do you think it could be the new mecoder? I dont think I have changed anything else in my system since I last tryed it.

However after more testing I still gets a lot of stuters with upscaling this way (ffdshow/avisynty) I still find using that beta with the mecoder upscaling to have the best perforamce, any chance you could change that back to how it was in the beta shagrath?
